Detailed Description

Reference numerals in the drawings of the specification include: the end seat comprises an end seat 1, a guide rod 2, a force application member 3, a mounting end 4, a fixing member 5, a nut 6, a connecting hole 7, a mounting hole 8, a through hole 9 and a ring groove 10.

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

Examples

As shown in fig. 1 to 3, the present embodiment provides a positioning pin quick-removing tool, including: the end seat comprises an end seat 1, a guide rod 2, a force application member 3, a nut 6 and a fixing member 5. The end seat 1 is a steel plate with a regular polygon structure, so that rotation of an assembler is facilitated. One end of the guide rod 2 is connected with the end seat 1, and the other end of the guide rod 2 is a mounting end 4. External threads are arranged outside the mounting end 4, and a connecting hole 7 for mounting the fixing piece 5 is formed in the end face of the mounting end 4.

The nut 6 is used for fixing the fixing piece 5 and the guide rod 2, and a mounting hole 8 for the guide rod 2 to enter and a through hole 9 for the fixing piece 5 to pass through are formed in the nut 6. The diameter of the fixing piece 5 is smaller than that of the guide rod 2, the diameter of the through hole 9 is smaller than that of the mounting hole 8, the mounting hole 8 is a threaded hole, the through hole 9 is a smooth hole, and the through hole 9 and the mounting hole 8 are communicated along the same axis. The guide rod 2 and the fixing piece 5 are detachably connected through the nut 6, so that the fixing piece 5 can be conveniently replaced when damaged.

The force application part 3 is sleeved on the guide rod 2 and is in clearance fit with the guide rod 2, and the outer diameters of the nut 6 and the end seat 1 are larger than the diameters of the force application part 3 and a matching hole of the guide rod 2, so that the force application part 3 is prevented from falling off from the guide rod in the process of taking out the positioning pin. The force application part 3 is in a cylindrical shape, and a ring groove 10 is formed in the outer cylindrical surface of the force application part in order to facilitate an operator to stir the force application part 3.

Through threaded connection between mounting 5 and the locating pin, mounting 5 is hexagon bolt in this embodiment, and end base 1 is regular hexagon or regular octagon, and connecting hole 7 is for being used for the interior hexagonal hole that hexagon bolt tip got into, and the locating pin tip is offered and is used for the screw hole of being connected with hexagon bolt screw thread section.

During the concrete implementation, the threaded section of hexagon bolt inserts in the threaded hole on the locating pin with locating pin threaded connection, then moves application of force piece 3 repeatedly with the hand and strikes end seat 1 for the locating pin is taken out gradually.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the utility model. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
